摘要
根据单桩静载荷试验及桩身轴力的测试结果,深入分析了竖向荷载作用下挤扩支盘桩的荷载传递机理和变形特性;同时给出挤扩支盘桩的单桩承载力计算公式。通过分析计算,指出了支盘的承力特性具有明显的时间效应和端承性质,揭示了支盘桩高承载力和S型Q-S曲线的内涵。
Based on the results of static loading tests and measurement of axial forces, the load-transferring mechanism and deformation behavior of vertically loaded squeezed branch piles are investigated and discussed in this paper. An equation is developed to calculate the vertical bearing capacity of a single pile. The obvious time effect and end-bearing behavior of bearing disks are pointed out by means of analysis. The high bearing capacity and S-shaped Q-S curve of squeezed branch piles are highlighted.
